2 Claims.

The present invention relates to chair seats or the like and moreparticularly to upholstered chair seats or chair backs. The structureshown and described herein is in the nature of a modiication of theconstruction shown in my copending application for patent filed March10, 1938, Serial No. 195,013.

The primary object of the instant invention is to provide a chair seat,chair back or the like having an upholstered covering detachably securedthereover in .a novel manner whereby worn coverings may be removed andnew ones substituted from ytime to time.

An illustrative embodiment of the invention is shown in the accompanyingdrawings, wherein:

Figure 1 is a top plan view of an upholstered chair seat, a portionthereof being broken away but it will be understood however that a chairback or the like may be similarly covered with a detachably securedupholstered sheet;

Figure 2 is a front elevational view thereof;

Figure 3 is a fragmentary side elevational view of the upholstered chairseat;

Figure 4 is an enlarged sectional View on line t-L'I of Figure 2;

Figure 5 is an enlarged sectional view on lines 5-5 of Figure 1;

Figure 6 is a view showing the manner in which the meeting ends of thesecuring wire may be fastened together;

Figure 7 is a view thereof after the meeting ends of the securing wirehave been fastened together;

Figure 8 is a view showing how the meeting ends of the securing wire maybe separated in instances wherein it is desired to replace a wornupholstered covering with a new and fresh one;

Figure 9 is a, plan View of the securing wire; and

Figure 10 is a side elevational view thereof.

Referring then to these drawings wherein like parts of the structureshown are designated by the same numerals in the several views, asupporting member for a chair seat, chair back or the like, here shownas an open top box of stamped sheet metal having vertically disposedside and end walls IE), has a peripheral groove II along the upperlength of each side and end wall (see Figure 5). The polygonal groove IIhere shown has a rounded rearward portion, rounded corner portions andstraight side and forward portions as best shown in Figure 1.

A chair seat I2 of hair or the like whose top, sides, ends and a portionof its bottom are enclosed within a fabric covering I3, is supportedupon a flexible element I4 of any suitable material such as stampedsheet metal whose borders rest upon the borders of the open top seatsupporting box, all as best shown in Figure 5.

An upholstered covering I5 for the chair seat I2 has a wire I6 sewedwithin the borders thereof which wire is of the shape best shown inFigure 9 and generally conforms to the shape of the polygonal groove IIlbut differs therefrom in that three of its lengths are inwardly sprung.

The upholstered covering I5 is detachably secured over the top, sidesand ends of the seat I2 by means of the wire I6 which is first insertedand seated within the groove II and thereafter secured together at itsmeeting ends in any suitable manner such as is shown in Figures 6 and 7.

The upholstered covering I5 may be similarly removed when it is desiredto replace it with a ynew covering by separating the meeting ends of thewire I6 as indicated in Figure 8. Since the wire I6 is sprung inwardlyalong three of its lengths, these inwardly sprung portions tensionallyengage within the groove II to stretch the upholstered covering I5 overlthe chair seat I2 since it is impossible to completely straighten theinwardly bowed portions of the wire by securing it together at itsmeeting ends.

Thus it will be seen that a chair seat, chair back or the like of thecharacter herein shown may be provided with an upholstered coveringwhich may be readily detachably secured thereover and while but onespecific embodiment of the invention has been herein shown anddescribed, it will be understood that certain detalls of theconstruction shown may be altered or omitted without departing from thespirit of the invention as the same is defined by the following claims.

I claim:

1. A polygonal rim having a peripheral groove, and an upholsteredcovering secured across the rim and whose entire peripheral border isprovided with a sewed-in ilexible wire conforming generally to the shapeof the polygonal rim but differing therefrom in that at least one lengththereof is normally inwardly sprung, said wire being first insertedwithin the groove and thereafter secured at its meeting ends fordetachably seating it within the groove to stretch the covering oversaid rim.

2. A open top supporting box for a chair seat or the like whoseupstanding peripheral wall is provided with a polygonal groove, aflexible member seated on the box over the open top thereof, a seat orthe like supported on the flexible member, and an upholstered. coveringfor the being first inserted within the groove and thereseat Whoseentire peripheral border is provided after secured at its meeting endsfor detachably with a seWed-in flexible Wire conforming genseating itwithin the groove to stretch the covererally to the shape of thepolygonal groove but ing over said rim. diiering therefrom in that atleast one lengthof 5 HENRY P.
